REPRODUCTION 0F MAPS AND THE LIKE.

Specification of Letters Patent.

Patented April 21, 1908.

Application led August 31, 1906. Serial No. 332,747.

T 0 all whom it may concern:

' Be it known that I, EDWARD ABERLE, a citizen of the United States, anda resident of the borough of Brooklyn, county of Kings, city and Stateof New York, have invented certain new and useful Improvements in theReproduction of Maps and the Like, of which the following is aspecification.

My invention relates to the reproduction of maps and the like bylithography and like rinting or manifolding processes, and has or itsspecial object to facilitate the putting in of words and lettering andat the same time secure a very clear impression of such words orlettering.

My invention is applicable to the lithographic process in which thedrawing on stone is, made with lithographie ink, and to the process inwhich the matter to be printed is etched into the surface of the stone.

I will now give a detailed description of my invention as applied to thefirst mentioned process.

The accompanying ure 1 a plan view of a tool applying the lettering;Fig. 2 is a vertical section on line 2 2 of Fig. 1 g Fig. 3 is a partialface view of such tool; Fig. 4 is a plan view showin T a lithographiestone with another form of my tool in position; and Figs. 5 and 6 arevertical sections on lines 5-5 and 6--6 respectively of Fig. 4.

I first produce the line work of the map on the stone A, either bydrawing directly on the stone, or by any suitable transferring or otherprocess. The insertion of words or letters is done subsequently by meansof a tool of the character of that shown in the drawings. The form ofthe tool represented in Figs. 1, 2 and 3 comprisesa plate or table Bwhich is adapted to form a handle through the medium of which theoperator or draftsdrawing shows in Figman may move the tool from placeto place and press it against the stone A on which it rests by means ofthe legs O, preferably rounded at their lower ends to facilitateshifting the tool without scratching the stone. Upon or adjacent to thetable B is a guide D for the vertical movement of a stamp comprising aholder E provided with a handle F and exchangeable type Gr made ofelastic material such as rubber. A spring H normally keeps the stamp inits raised position, (with the holder E abutting against the undersideof the table) and an adjustable `stop I working in conjunction with afinger J devised by me forl on the stamp, limits the downward movesureof the type against the stone and enable the operator to obtainsubstantially the same amount of pressure at each depression of thestamp.

The edge of the table B adjacent to which the stamp is located forms aguide enabling the operator to properly place the tool on the stone, orif he does not think this accurate enough, he may put a ruler or otherstraight bar on the stone against the two legs C which are at the endsof the said edge.

The type will be inked, and ought to differ from ordinary type in thatit will not be reversed, but will have an appearance like printedcharacters. The impression produced on the stone by such type willtherefore be reversed, that is, it will have the same appearance asordinary print seen in a mirror. Of course, in printing from such astone the letters will be reversed again, so that they will have theordinary appearance. The elasticity of the type will enable it toconform to the surface of the stone, and a very sharp outline will beobtained. Owing to the provision of the stop I the same amount ofpressure will always be applied to the type, insuring a degree ofuniformity which otherwise would be practically impossible even withconsiderable skill. The operator would adjust the stop until a specimenimpression made with the stamp shows that the right amount of pressure1s being exerted; after this, no adjustment will be required, butnotwithstanding the ra idity of the work, uniformly sharp and c earresults will be obtained. Of course, the type may form a straight lineor a curved line as required, holders for the one kind or the otherbeing well known. The stamp proper is removable from its guide l) sothat stamps of various kinds may be used as the work may call for. Forthis purpose the stem F of the stamp moves in a (triangular) guidewayopen on the face of the guide D, and a movable spring kee per or slide Kis employed for temporarily holding the stamp in its guideway. Bysliding the keeper K to the left in Fig. 3, the stamp is released sothat it can be withdrawn forward.

In the construction illustrated by Figs. 4L, 5 and 6 I employ twoparallel guides L L along which is adapted toslide a carriage consistingof two members M M connected by a cross-bar M2. One of the members, M,

PATENT oEEIcE.

nient of the stamp so as to regulate the pressimply rests on its guideL, the other member M being held by one or more retaining bars M3. Theguides L L are supported by legs L2 and held by braces L3. On thecrossbar M2 a slide N is movable transversely, and the lower section Nof this slide is made with a screw-thread in engagement with afeed-screw O rotatably mounted in the cross-bar M2. To' the slide N ispivoted at P an arm D which is similar to the guide D in that it has aguideway for the stamp, and this guideway and stamp may be constructedexactly as in the form of the tool first described. The arm D may havean arc D2 engaging a projection N2 of the slide so as to brace the armas the stamp is pressed down. With this second form of my tool, thestamp can be adjusted readily to any portion of the stone A, and byturning the arm D on its pivot P, the stamp can be placed at any desiredangle, and secured in such position, if desired, by tightening the pivotscrew and thus clam ing the arm.

When t e invention is used in connection with the process in which thelines are etched into the stone, metal types would preferably be used toform an impression in the wax or other temporary protective layercovering the stone. These types would of course not be inked, but inother respects the manner of carrying out Iny inventlon would be thesame as described in connection with the other process, that is, thetype would be facing like print instead of being reversed, and the stopwould govern the pressure so as to render it uniform at each operationand secure clear and even impressions.

What I claim and desire to secure by Letters Patent is:

l. The herein described process of reproducing maps and the like, whichconsists in first applylng the line-work to a plate or surface, thenstamping entire words or abbreviations on the plate or surface at onetime and limiting the pressure applicable during this operation so thatevery letter of every wordA or abbreviation will receive the same amountof pressure, preparing the plate for printing, and making an impressiontherefrom.

2. The herein described process of repro ducing maps and the like, whichconsists in first applying the line-work to a plate or surface, thenstamping the lettering on the plate or surface while limiting thepressure applicable during this operation, preparing the plate forprinting, and making an impression therefrom.

In testimony whereof, I have hereunto signed my name in the presence oftwo subscribing witnesses.

EDWARD ABERLE.
